Title: Vacuum load-break switch
Inventor: MATSUYAMA KIYOSHI
IPC: H01H33/66
Filed: 1988-12-19
Abstract: PURPOSE:To simplify attachment of a vacuum switching tube and also simplify the structure of an insulating frame by causing the vacuum container of the vacuum switching tube to be constituted of a metal tubular body, a bellows and a flat-plate-shaped insulating plate and attaching the insulating plate to the attaching portion of the insulating frame. CONSTITUTION:Fixed electrodes 3 for three phases are each vacuum-hermetically sealed to a flat-plate-shaped insulating plate 10 in such a manner as passing therethrough, and attached in such a manner as for insulation between each fixed electrode 3 and each moving electrode 5, and the insulating plate 10 forms a part of the vacuum container 8 of a vacuum switching tube 1. Since the vacuum load-break switch is formed simply by attaching the insulating plate 10 to an attaching portion 11a, the vacuum switching tube 1 is easy to operate. Since that portion of the insulating frame 11 which the periphery of the insulating plate 10 overlaps can be used as the attaching portion 11a, the structure of the insulating frame 11 can be simplified.

If the fluorination is performed in the liquid phase, a catalyst such as SbF5 or NbCl5 is used. Fluorodichloromethane, difluorochloromethane, trifluoromethane, etc., which are fluorinated substances are then removed to afford the subject purified substance.

Title: Separator for electrolytic capacitor
Inventor: YAMAZAKI MITSUHIRO
IPC: H01G9/02
Filed: 1987-12-18
Abstract: PURPOSE:To make it possible to manufacture an electrolytic capacitor characterized by a low equivalent series resistance value and excellent sound quality, by including floss silk in at least a part. CONSTITUTION:The raw material of floss silk is cocoons. The thickness of the fiber is as thin as 1/5-1/100 that of Manila hemp. The bends of the fiber is complex. The thickness are not uniform. Only the floss silk can hold sufficient amount of electrolyte by cutting, beating, paper manufacturing and so forth. Since the quality is close, an electric resistance can be made small when the electrolyte is impregnated. When the floss silk is mixed with vegetable fiber such as Manila hemp and craft in order to increase mechanical strength and to make mixed paper, the floss silk fiber is finely entangled in the gaps between the thick fibers of the Manila hemp and the craft. Thus the very thin gaps are formed. The withstand voltage of a separator, which is electrolytic paper, is improved. When the separator including the floss silk fiber is used, repelling force is less since the separator is soft against minute bending force caused by vibration. Therefore, deterioration in audio signals and distortion in sound quality can be prevented.

Title: Differential device and manufacture of disc-form member used in the device
Inventor: MIMURA KENJI
IPC: F16H48/12
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a differential device to set the magnitude of a differential limit force to respective different values according to the transmission direction of a rotation force. SOLUTION: In one transmission direction of a rotation force, a contact angle between a ball 5 on the inside in the radial direction of one disc plate 3 and a groove is βi1 and a contact angle between the outside in the axial direction of the other disc plate 3 and the groove is βo1. In the other transmission direction of a rotation force, a contact angle between a ball 5 at the outside in the radial direction of one disc plate 3 and the groove is βo2 and a contact angle between the inside in the radial direction of the other disc plate 3 and the groove is βi2, and the magnitudes of the contact angles are set βo1>βo2 and βi1>βi2. Since a reaction force in the direction of a rotary shaft in one transmission direction of a rotation force, i.e., a thrust force E1 , is increased to a value higher than a thrust force E2 in the other transmission direction of a rotation force, differential limit forces differed in a magnitude with the transmission directions of the rotation force are generated.

Title: Video signal processor
Inventor: SUENAGA SHINICHI
IPC: G11B5/027
Filed: 1987-12-17
Abstract: PURPOSE:To attain memory control not causing defective synchronization with an input video signal at the release of still picture reproduction by correcting an address control signal from the result of calculation of a phase difference between a synchronizing signal of an input video signal and an address control signal. CONSTITUTION:A correction value operating circuit 9 in the read mode receives a vertical synchronizing signal (e) and an address control signal (c) outputted from a memory controller 5 and measures the phase difference between the input video signal (a) and an output video signal (i) to output the phase lead or phase lag to the memory controller 5 as a correction value (j). When the phase of the output video signal (i) is led than the input video signal (a), the memory controller 5 retards the count-up of the address control signal (c) and when retarded, the controller 5 advances the count to decrease the phase difference between the output video signal (i) and the input video signal (a). Thus, an excellent pattern without any disturbance on the monitor screen is obtained without causing vertical asynchronization at the release of still picture reproduction release.
